Blue Ground vs Agua Fría
Blue Ground (Farrow & Ball) and Agua Fría (Sherwin-Williams) come from different manufacturers. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 49 vs 52 — so neither will read significantly brighter or darker than the other. Both share a cool character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 2.2 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Blue Ground vs Agua Fría in Real Spaces
3 real rooms side by side. Blue Ground and Agua Fría are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.

Blue Ground vs Agua Fría Simulated Comparison
5 simulated room previews — drag the slider on each to see Blue Ground on one side and Agua Fría on the other.
Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
